of the LC8 AC Servo Motor Controller. The LC8 is a servo
amplifier/controller for the LJ, LG, and LTF series
actuators and provides high level features at mid-level
Up to seven LC8s can be slaved together for control
from a single PLC, which can execute 117 steps that
can command any or all of the actuators to move to a
specific position, move a specific distance, or apply a
specific amount of torque. The position accuracy is
±0.005 mm to ±0.025 mm, depending on the feed screw
lead of the actuator. There are also five palletizing steps
that can use the same command from the PLC to
move two axes sequentially through pallets of up to
10,000 rows by 10,000 columns. The simple method for
configuring and running the palletizing features has been
awarded a US patent.
The LC8 comes with easy-to-use human/machine
interface software for configuring and testing the
controllers. This HMI software includes features for
“teaching” positions by moving the actuators either
manually or under power. All of the configuration data
can be stored in files so that a setup for one machine can
be easily duplicated on many others.
The LC8 is compact (141 mm x 75 mm x 130 mm),
weighs less than 1 kg, and is available for 100-15 VAC or
200-220 VAC power and either 50, 100, or 200 watt
motors.SMC Corporation manufactures high quality
electric actuators and controllers for industrial automation. SMC has a total of 14 production facilities, three of
which are in North America.

SG5-UT (Ultra Torque) Series
Inc., has released
its new SG5-UT series,
load balanced, robotic arm, featuring
all-aluminum construction and the only
fully-expandable “smart grip” design
components (details following).
Feature for feature, the SG5 series
presents the most powerful,
sophisticated, all-aluminum, five-axis robotic arm system available
38 SERVO 07.2004
• All parts are precision CNC machined from .063 gauge,
5,052 brushed, sheet aluminum.and are anodized to a
smooth, scratch-resistant, graphite finish using a type II
anodizing process (the hardest finish possible, next to
military spec type III anodizing).
• All servo pivot points use integrated pem stud pressed
pivot points, not taped or glued.
• Integrated pem nuts ease construction.
• The arm incorporates a custom engineered, counter
balanced retract system that effectively ensures
maximum lifting capability and efficient servo power use
during operation and at rest.
• Pass through holes and slots are strategically located
throughout the arm assembly for convenient wire
• Two integrated SPST switches provide convenient power
routing to servos and supporting electronics.
• Three integrated mounting tabs offer convenient
attachment to your robotic platform.
• The arm accommodates all of the Parallax microcontroller boards.
We developed the critical design of the gripper
assembly to include the following critical design features:
•The gripper assembly contains integrated, adjustable
electronics that are located above the gripper assembly to
accommodate an array of CCD cameras, infrared sensors,
and other sensing electronics. The
gripper contains four integrated slots to accommodate
multiple sensing optoelectronics components. The ends of
the gripper are rounded for an even gripping surface. The
gripper drive system consists of a high resolution, 60
tooth, heavy duty, resin geartrain driven by a high torque
Hi-Tec HS 475 servo.
•The rounded gripper ends can conveniently
accommodate the “Flexiforce” pressure sensor for precise
gripper pressure measurement and control (sensor not
included). A 1/16” volara, cross-linked polyethylene foam
is used to line the inside of the gripper surface for maximum grip adhesion. The inside width of the gripper is 3. 25
x 3. 25 x 1.125 inches and the arm is 17. 75 inches high.It
can rotate 180° on its base and lift 14. 23 oz.
•The arm has three Hi-Tec HS-475 HB high torque
servos for the rotating base, wrist, and gripper and three
Hi-Tec HS-675MG (metal gear) ultra torque servos for the
shoulder and elbow drive systems.The arm uses the
Parallax Board of Education (BOE), BASIC Stamp 2 (BS2),
and an all-new, powerful, 16 servo, Parallax Servo
